Hello Everyone, I just bought into the above boat which is moored in a boat house in Sydney BC. My partners are nearly never around to use it so the maintenance will be up to me. Questions: 1) The 110V power plugs are dead though the shore power is hooked up and the main panel switch is on. Is there a hidden fuse panel somewhere? I found the one under the dashboard but none of the fuses are blown. 2) Since the owner's manual isn't available, does anyone know how many liters/gallons of water and gas it holds? Also, how do you know when the wastewater holding tank is full? 3) The tachometer doesn't work and there's a circular electrical connection suspended in the air above the coil. I'm afraid to reconnect it. Any thoughts? Thanks in advance.

The fuses under the helm are for the 12VDC systems and not the 110VAC power. When plugged in is power showing on the volt meter where the AC breakers are? I suspect the issues is behind this panel so you will have to remove it to inspect the connections. I'm not sure of your power requirements downunder, are they the same 110VAC 60 cycle as US? If not someone may have disconnected it to prevent issues instead of changing the system.

Regarding the tach does it work at all? Try rotating the engine select switch on the back from 4-6-8 a few times to see if the makes a difference. Are the connections good? The gray wire is the signal from the ignition, use a bolted meter to see if it reads anything, its pulsed but the meter will average it so you know the wire is good. The gauge may just be bad.

Post a picture of the circular connector you are seeing. The only one I know of is the ten pin engine connector but is disconnected the engine will not run.

Fuel tank is 102 gal, water is 30 gal and waste 16 gal!
There should be a GFI receptacle, check at all 110 volt outlets for a GFI and reset if tripped!
The holding tank you will have look at to tell if it needs to be pumped out!
Hope this helps!
I have the original owners manual for the 2400 and 2700 SCR's if you PM me with your email I will try to send the wiring diagrams!

Tachometer follow up: Where is the sender located on a 7.4 liter Mercruiser V8 engine? I assume I'll have to hunt down and locate the end of the Tach gray wire but wouldn't mind some guidance from the resident gurus.

The 7.4 has a distributor so the tach signal comes from the coil negative terminal. I'll try and post a wiring diagram tomorrow.
